Abstract

A process monitoring system includes: a plurality of field devices configured to measure state quantities in an industrial process implemented in a plant; a trend calculation unit configured to determine the variation trend of the state quantities based on time-sequence data output from each of the plurality of field devices and classify each of the variation trends of the state quantities into one of a pre-established plurality of statuses; a state change judgment unit configured to judge the existence or non-existence of a pre-indicator of a change in the plant state, in accordance with the existence or non-existence of a change in at least one of the statuses classified by the trend calculation unit; and a notification unit configured to notify of judgment results of the state change judgment unit.

Description

technical field [0001] The invention relates to a process monitoring system, device and method. [0002] This application claims priority based on Japanese Patent Application No. 2012-123948 filed on May 31, 2012, and uses the content for this application. Background technique [0003] It is only necessary to cite patents, patent applications, patent publications, scientific documents, etc. below for clarification, but to more fully describe the prior art of the present invention, the contents thereof are hereby cited. [0004] Currently, a process monitoring system for monitoring various state quantities (for example, pressure, temperature, flow rate, etc.) in an industrial process is constructed in a workshop, a factory, or the like. Based on the monitoring results of this process monitoring system, advanced automatic operation is realized. This process monitoring system is roughly composed of field devices (meters, manipulators) called field devices, a controller that c...
